To LM 'Lu/wm, it' 71u57/ concern:

Be it known that I, ANsLEY H. Fox, of the city and county ofPhiladelphia, State of Pennsylvania, have invented an Improvement inBreech-Loading Breakdown Guns, of which the following is aspecification.

My invention has reference to breech-loading breakdown guns; and itconsists of certain improvements which are fully set forth in thefollowing specification and shown in the accompanying drawings, whichform a part thereof.

My invention comprehends certain improvements in that class of firearmsknown as breech-loadingbreakdown guns and embodies an improvedconstruction and means for operating the hammers and sears whichsimplify and facilitate manufacture and accomplish other desiredresults, as hereinafter more fully set forth.

In the accompanying drawings, Figure l is a longitudinal sectional viewofthe breech portion of a gun embodying' my invention andillnstratingthe parts as they appear with the barrels broken down forloading and the locks cocked. Fig. 2 is an inverted plan view of thebreech-frame and other parts. Fig. 3 isa sectional elevation on line 3 3of Fig. 2, showing the means for settling the hammers; and Fig. 4 is across-section of same on line 4 4 of Fig. 3.

The barrels A are hinged to the breechframe B in the usual manner andare provided with a bottom lug A, dependent from the under side of thebarrels, which lug is preferably integral therewith. In this lug I placea cooking-plate C, which serves to engage with and lift the hammers D bytheir forward-extending arms D as the barrels drop for loading. The rearend of this cocking-plate forms a lug which rests normally below theextended arms of the hammers to move them, and said plate is secured tothe barrel-lug by means of a T-shaped extension O, guided in a T-slotO2, which extends longitudinally almost the entire length of the saidbarrel-lug A.

On top of the cooking-plate there is a small stud, against which aspiral spring' S is applied and held in place byascrew-plug S, so thatas soon as the fore-end iron R, which serves as an abutment for thefront end of the said cooking plate or slide, is removed the spring willforce the cocking-plate rearwardly and out of engagement with the hammerends, thereby allowing the barrels to be readily attached or detachedfrom the frame.

The hammers D are provided with the forwardly-extending arms D,which arebrought laterally inward, so that their forward ends lie normally in thebarrel-lug slot P in the center of the breech-frame, while their lrearends continue back at substantially right angles and serve to strike theprimers.

The hammer-arms D are turned laterally inward at a point just forward ofthe pin D2, on which they are pivoted, and directly under and in frontof the pivot-pin they are slotted to receive a toggle E, which serves toactuate a round plug or follower F for the purpose of compressing thespiral mainsprings G as the hammers are cocked. These springs areinclosed in parallel tubular apertures H', arranged in the forward partof the breechframe and respectively upon opposite sides of the slot Pfor the bottom lug of the barrels. They are in direct line with thestriking parts of the hammers, whereas the forward arms D of saidhammers are oppositely cranked, so as to come close togetherin the slotbetween the said springs Gr. The particular angular shape of the hammersis, moreover, important, as it enables the forward arms D extendingaround that portion B of the breech-frame in which the locking mechanismfor the barrels is located. Said locking mechanism is operated by therock-shaft W and4 lever W.

The hammers D are held in the cocked position by the engagement of thesears H in the manner shown, and the sears are kept up to their work bythe Sear-spring I, which consists of one flat piece of steel with twospring-arms I I extending rearwardly and resting, respectively, uponeach of the sears.

The scar-spring is held in normal position by one screw Q1, which drawsit down to the breech-frame, and thereby puts a tension upon both thesears H as the screw is screwed into place.

J represents the triggers, which have shoulders for tripping the sears Hto release the hammers. These triggers are pivoted at K and haveupwardly-extending arms J at the rear of their pivoted points. Arrangedin the Lipper part of the frame is a slide L, having a lug M extendingdownward and adapted to be moved over the arms J of the triggers IOO tolock them against movement to release the hammers. rI`he slide L has anextension terminating in a thumb piece L above the breech-frame and bywhich it may be shifted longitudinally into and out of locking position.To retain the slide L in either of its eXtreme positions, I make itsrear end inthe form of a spring N, with a head which is adapted to snapinto either of the depressions O. Any other means of retaining may beemployed in lieu of that shown.

It is obvious that numerous modifications of my invention may be madewithout departing from the essential points.

. That I claim as new, and desire to secure by Letters Patent, is-

l. In a hammerless gun of the class described, the combination of twobarrels having a barrel-lock provided with a cocking-lug,

and a breech-frame having a central opening close to and in line withthe barrel-lug and to which breech-frame the barrels are pivoted inadvance of the barrel-lug, two hammers pivoted to the breech-frame andhaving their forward ends turned laterally inward to a central positionadjacent to the cooking-lug so that they work close together side byside in a central opening in the breech-frame, toggles hinged to thehammers to each side of their forward lateral ends, and spiral springsfor operating the hammers through the tog-l gles arranged upon oppositesides to the cocking-lug and central openingl in the breechframe andforward lateral arms of the hammer. Y

2. The combination of the breech-frame, pivoted barrels having' acooking-lug, a springactuated cooking-plate, two pivoted hammers havingtheir forward ends turned laterally inward so as to work close togetherin a central position back of the barrel-lug, toggles carried by each ofthe hammers, spiral springs within the breech-frame on opposite sides ofthe barrel-lug and the forward ends of the hammers for operating thehammers through the toggles, and a fore-end iron having its under partextending forward to directly press against the cooking-plate and act asan abutment to hold it in operative position against the action of itsspring.

3. rIhe combination of a breech-frame havingacentral opening, twopivoted barrels having a cocking-lug arranged to be received in theforward end of the central opening of the breech-frame, two hammershaving the forward ends turned laterally toward each other so as to workclose together in the central opening' in the breech-frame in line withthe barrel-lug, spiral springs within the breechframe on opposite sidesof the barrel-lug and forward ends of the hammers for operating thehammers, and a cocking-lug carried by the barrel-lug to engage theforward arms of the hammers.

4. The combination of the hammers, two pivoted sears for controlling thehammers, triggers for operating the sears, and a searspring consistingof one piece having a body secured to the breech-frame betweenthehammers in advance of the pivots of the sears and having tworearwardly-extending spring-arms pressing upon the sears to the rear ofthe pivots.

5. In a hammerless gun, the combination of a breech-frame having acentral opening in the rear of the pivots of the barrels with thebreech-frame, two spring-actuated hammers provided with laterallyarranged forward arms and in which the arms of the respective hammersextend laterally in opposite directions so as to come close together andoccupy the central opening in the breech-frame, a cooking-lug movablewith the barrels and engaging the forward ends of the arms of thehammers and also working through said central opening whereby thehammers are moved to cocked position when the barrels are broken down,and spring devices for operating the hammers located upon each side ofthe central opening in the breech-frame.

6. In a hammerless gun, the combination of a breech-frame having acentral opening in the rear of the pivots of the barrels with thebreech-frame, two spring-actuated hammers provided with laterallyarranged forward arms and in which the arms of the respective hammersextend laterally in opposite directions so as to come close together andoccupying the central opening in the breech-frame, a sliding plateforming a cocking-lug and carried with the barrel-lug for engaging theforward ends of the arms of the hammers whereby the hammers are moved tocooking position when the barrels are broken down, a spring to move thecooking-plate out of engagement with the hammer-arms, and a foreend irondirectly acting upon the cockingplate itself for holding' it inoperative position against the spring in the assembled condition of thegun.

7. Inahammerless gun, the combination of the breech-frame, two hammers,pivoted barrels, a lock for the barrels, a spindle to operate the lockat the rear of the breech-frame, two sears for the hammers, triggers foroperating the sears, and a V-shaped scar-spring having the two armsrearwardly extended to straddle the locking operatingspindle andpressing upon the sears and the intermediate portion screwed down to thebreech-frame intermediate of the hammers.

In testimony of which inventionI hereunto set my hand.
